Method Detail

anticipate

NeighborTriplet anticipate(NeighborTriplet neighborTriplet,
                           Duration duration,
                           Length traveledDistance,
                           boolean downstream)

Anticipate movement.

Parameters:

neighborTriplet - NeighborTriplet; headway, speed and acceleration

duration - Duration; duration

traveledDistance - Length; distance the subject vehicle traveled during the anticipation time

downstream - boolean; whether the perceived GTU is downstream

Returns:

anticipated info

egoAnticipation

Length egoAnticipation(Speed speed,
                       Acceleration acceleration,
                       Duration duration)

Anticipate own movement.

Parameters:

speed - Speed; current speed

acceleration - Acceleration; current acceleration

duration - Duration; anticipation time

Returns:
